serum turning brown- OK to use?
I stopped using the lightening serum for a while but then noticed some spots from being outside this summer so got it back out but noticed its turning brown. I feel bad tossing it because half of the serum is left and its pricey. Will it still work if its changing color? Will anything bad happen from using it this way?
